The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.
As shown in fig. 1-2, a vertical mill for producing machine-made sand comprises a speed reducer 6, a motor 5 arranged on one side of the speed reducer 6, a housing 1 fixed on the upper end of the speed reducer 6, and a grinding disc 2 fixed on an output shaft of the speed reducer 6 and transversely arranged at the bottom inside the housing 1, wherein a rotating shaft of the motor 5 is connected with an input shaft of the speed reducer 6; the shell 1 is at least provided with two grinding components which are distributed at equal angles along the circumferential direction, and each grinding component comprises a rack 7, a pressurizing cylinder 8, a rocker arm 9, a grinding roller 10 and a main shaft 12; the grinding disc grinding machine is characterized in that a rack 7 is arranged on the outer side of a shell 1, a rocker arm 9 is rotatably connected to the upper end of the rack 7, a telescopic end of a pressurizing cylinder 8 is rotatably connected to the lower end of the rocker arm 9, a fixed end of the pressurizing cylinder 8 is rotatably connected to the lower end of the rack 7, a main shaft 12 is arranged in the shell 1 in an inserting mode, the outer end of the main shaft 12 is fixed to the upper end of the rocker arm 9, a grinding roller 10 is concentrically and rotatably sleeved at the inner end of the main shaft 12 and arranged above a grinding disc 2, the vertical distance between the lower side of the circumferential side face of the grinding roller 10 and the upper plane of the grinding disc 2 is 10-50 mm when the lower side of the circumferential side face of the grinding roller is parallel to each other, a plurality of scraping plates 3 which are distributed at equal; the top of the shell 1 is also inserted with a vertically distributed feed pipe 11.
The ratio of the outer diameter to the thickness of the grinding roller 10 is 1-5; the specific grinding pressure of the grinding roller 10 (namely the grinding force/(roller width roller diameter) of the grinding roller 10 on the material on the grinding disc 2) is 0.1-0.7 MPa.
The working principle is as follows: the raw material enters the shell 1 through the feeding pipe 11 and falls onto the grinding disc 2, the rotating shaft of the motor 5 drives the input shaft of the speed reducer 6 to rotate, and then the grinding disc 2 is driven to rotate by the output shaft of the speed reducer 6, so that the raw material is driven to move towards the edge of the grinding disc 2 by centrifugal force, when the raw material moves between the grinding roller 10 and the grinding disc 2, the raw material is crushed under the extrusion of the grinding roller 10 and the grinding disc 2, and meanwhile, the grinding roller 10 is driven to rotate passively; because the vertical clearance between the lower side of the grinding roller 10 and the upper plane of the grinding disc 2 is 10-50 mm, the direct contact between the grinding disc 2 and the grinding roller 10 is avoided, and the proper material bed thickness can be established between the grinding disc 2 and the grinding roller 10, so that the vibration is small during operation and the sand making efficiency is high; the milled materials continuously move towards the edge of the grinding disc 2 under the drive of the grinding disc 2 until leaving the grinding disc 2 and falling to the inner bottom of the shell 1, and move to the upper part of the discharge port 4 under the drive of the plurality of scraping plates 3 and are discharged outwards through the discharge port 4; the interior of the shell 1 adopts micro negative pressure for dust collection, so that the production environment is better, and the dust pollution is less; the surface of the grinding disc 2 is of a plane structure, which is beneficial to discharging the material ground by the grinding roller 10 out of the grinding disc 2, and excessive fine powder below 0.075mm generated by over-grinding is avoided.
The telescopic end of the driving pressurizing cylinder 8 extends outwards, and the outer end of the main shaft 12 is driven by the rocker arm 9 to swing up and down, so that the inclination angle of the grinding roller 10 is adjusted to achieve a more proper grinding angle.
